Son River which is one of the largest southern tributaries of Ganga originates in which state?

  1. A.West Bengal
  2. B.Uttar Pradesh
  3. C.Assam
  4. D.Madhya Pradesh

Correct answer

D. Madhya Pradesh

Explanation

The correct answer is D, Madhya Pradesh. The Son rises at Amarkantak on the Maikal hills in Anuppur district of Madhya Pradesh, the same plateau from which the Narmada starts in the opposite direction. It flows north and then east for about 780 km through Madhya Pradesh, Uttar Pradesh and Bihar, and joins the Ganga near Maner, a little west of Patna. It is the largest right-bank (southern) tributary of the Ganga; its own tributaries include the Rihand and the North Koel, and the Bansagar dam in Madhya Pradesh and the Rihand dam in Uttar Pradesh stand on this system. The famous Koilwar rail-road bridge in Bihar crosses the Son. A is wrong because West Bengal is where the Ganga ends its Indian course, not where the Son begins. B is wrong because Uttar Pradesh only lies on the Son's middle course. C is wrong because Assam belongs to the Brahmaputra basin. Exam tip: Amarkantak sends the Narmada west and the Son north-east; the Son meets the Ganga near Patna.

Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.
